IBM Enterprise Integrator - Replication Activity

We have created a replication activity to transfer data from Notes to an SQL 2016 server database. The activity uses ODBC13 driver for connection. The activity runs fine when its run on a blank table but it keeps on running for all subsequent runs. So, it pushes data for the first time and for all subsequent runs it just keeps on running.

What could be going wrong here?

EDIT: I have been able to narrow down the problem to use of computed for display fields in the LEI connection. I am using computed for display to compute values on the fly and then use those fields to as source fields in the activity. If I remove the computed for display fields from the activity then it runs fine.

Does use of computed for display fields cause problems in a replication activity? It seems to work fine in a Direct Transfer activity.

Subject: OPTIONS

Do you need replication to just do deltas or maybe a direct transfer will be better? If you need replication then what options do you have for the key and add deletes and updates?
